I This invention relates to improvements in A further ob 'ect of this invention, is the provision of an improved hinge adapted to be used in connecting the sections'of ventllating flooring of refrigerator carsand the like,

so that the sections of the, said flooring may be positioned to act as flooring in the car, against liability of relative shifting; or so that one of the sections may be collapsed on top of the other out of the position of the doorway, which is desirable under certain circumstances understood by those skilled in the art; and so that the sections of the flooring maybe compactly collapsed together for positioning in an out of the way location where the same will occupy but little space.

A further object of this invention is the provision of a reversible type of hinge, in-

cluding members adaptablefor connection together in a novel relation to each other and to a pair of sections to be hinged together. Other objects and advantages of this invention will be apparent during the course of the following detailed description. 7.

B may generally designate sections of false or ventilating flooring which-are adapted to be connected by the improved hinges C in such relation that the flooring sections A surface facing relation. p

The section A whlch maybe referred to as I a main section is constructed as inconven and B' may be entended-in the same plane,;or.

may be collapsed in top surface'facing'relae tion, or may be collapsed in compact bottom t-ional manner, with longitudinal spaced parinatss allel stringers 10 and 11, having the cross platform pieces 12 secured thereto in any approved manner, in preferably edge spaced "relation at. right angles to the stringers 10;

it being understood that the stringers 10 and 11 depend below the under surface of the" M J r The section B may be referred to as-a door cross pieces 12. a

section adapted to be placed in position between-the opposed doors on arefrigerator car or the like, so that ittmay beconveni ently-l removed or folded back upon the section A, as will. be well understood by those skilled in The section B; preferably includes I v stringers 14 and 15, having the. crossplat-F Y the art.

form pieces lZ connectedthereon in spaced relation. The cross p1eces17 are so, connected upon the stringers 14 and 1 5, that the lat-' ter when hingedly connected with the stringers 10 and'll of the section A, are QL'ltOflQn V gitudinal alignment with the stringers lO and and 15'to be collapsed side by side with the under surface of-the sections A and} B in factions A and one: hinge connecting the stringers lland 15 and the; other hingeB v a connecting the other stringers 10 and 14 as is l illustrated in Figurel of thedrawings. The hinge C includes the elongatedbodies or shanks 20 and 21, whicharepreferably straight forkthe major length thereofpand adjacentytheir pivoted ends they are pro-l videdwith oifset ends 22 and. 23 respectively,

'which are in .a .J-shaped' relation with the shank body; the ends 22 and 23 being transversely arranged in an acute angle relation to the shank portions" 20 and 21 with which they are respectively integral. At the outer ends of the end portions 22 and 23the same are connected by means of a pivot belt or.

pintle 25, and to space the ends 22-and 23 from rubb ng on each other a hub26 may be provided about the opening 27 in the end 22,:

which abuts against the facing side of the end portion 23 of the section 21 and the end 23 may have a similar hub 29 thereon facing away from the end portion 22, this hub 29 having a passageway 30 therethrough through which a reduced hub 31 of the end 22 extends; it being understood that the passageway 27 thus receives in contacttherein ing transverse alignment the bodies 20 and 2110f the hinge C are in a divergent relation,

as illustrated in Figure 2 of the drawing Near their outer ends the body portions 20 and 21 are provided with transverse hub extensions and 41, having passageways therethrough for receiving pivot pins or bolts to be subsequently mentioned. At their extreme ends the bodies 20 and 21 are provided with reduced obtusely arranged ends 43 and 44, the edges-'45 of which are obtusely arranged, out of alignment with the edges 46 of the bodies 20and 21, to accommodate an arrangement of thesections A and B obvious from the illustration.

'Referringto the matter of attachment of the hingeparts on the sections A and B, the

stringers 10, 11, 14 and 15, on the sides 'of which the hinges are connected, are provided with angle-shaped wear plates 50, which are secured by means of bolts 51 to the stringers, and, which provide side wear plate portions along, the sides of the stringer and a top'wear plate portion against which the edges 45 and 46'of'the hinge bodies abut during positioning of the sections A and B in various collapsed or extended relations. 7

. The bodies 20 and 21 of the hinge C .are'piv-' otally connected by detachable bolts or pintles 55 to the respective stringers of the sections A and. B, so that each hinge has'abody portion 20 thereof'connected toan outer or inner side ofthe stringer of one section and the body portion 21 ofsaid hinge is connected to the inner or outer stringer ofthe other section, so that in anyevent the hinge C will offset the stringers of the sections A and B in a nonaligning relation, so that the stringers may be collapsed parallel with the undersurfaces ofth'e platform sections facing, as is illustrated in Figure 4 of the drawing. f

During the normal extended positioning of the platform sections A and B it is to be noted that the hinge bodies 20 and 21 are pivotally connected by the pintles or bolts 55,

so that the bodies 20 and 21 converge down-- wardly fr m said pintles 55, and the end portions 22 and 23 are upturned in transverse conforming relation, and the pintle 25 is mentioned offset end portions.

disposed below the top surface of the platform sections, now disposed in the same plane.

essary to lift the section B and incident tothe arrangement of the hinges the bodies 20 and 21 will pivot on the pintles 55 and permit the top surfaces of the cross platform pieces 12 and 17 of the sections A and B to come into abutment, asis illustrated in Figure 3, and this places the stringers of the section B uppermost,'and the edges 46 of the'bodies 20 and 21 abut against the under surfaces of the top flanges of the wear angles 50, to take the wear and limit liability of'damage to the platform or floor sections incident to such collapsing. In event it is desired to remove the floor sections A and B for storage, or to an out of the way location, it is merely necessary to swing the same inwardly with their under surfaces in facing relation, and since the stringers are out of aligning relation they maybe collapsed parallel side'by side, and in this position the edges 45 of the bodies 20 and 21 come into abutment with the under surfaces of the top flange of the wear angles 50, as illustrated in Figure 4, and the bodies 20 and 21 of the hinge parts are inan X-shaped relation.

From the foregoing description of this in vention it .is apparent that-a novel type of hinge'has been provided,(particularly well adapted for use in connecting a pair of floor sections of the general character referred to. Various changes in the shape, size, and arrangement of parts may be made to the form of invention herein shown and described, without departing from the spirit of the same or thescope of'the claims.

We claim:

1. In a hinge the combination of a pair of elongated shanks, said shanks each having an offset end portion, means pivotally connecting'the outer ends of said offset end'portions,

so that each of said end portions may swing to either side of the axis of the other, said shanks at the opposite ends being provided with end portions extending in a direction opposite 0n the respectivebodies to the first i 2. As an article of manufacture a hinge construction comprising a pair of substan tially J-shaped members including elongated substantially straight body portions having shorter transverse acute offset ends, pintles pivotally connecting the outer ends of said ofiset ends, said elongated bodies having substantially straight counter moving edges from their offset endstowards their opposite ends and at their opposite ends having obtusely arranged straight edges.

3. Ina device of'the class described thecombination of a pair of sections having depending stringers therebelow, a hinge including a pair of substantially J-shaped shanks including elongated straight body portions and transversely offset end portions,

a pintle connecting the offset end portions at the outer ends thereof, and pivot members pivotally connecting said shanks at their opposite ends on the stringers of said sections.

a. In a deviceof the class described the.

combination of a-pair of sections having'depending stringers therebelow, a hinge including elongated straight body portions and transversely offset end portions,a pintle connecting the offset end portions .at the outer ends thereof, and pivot members pivotally connecting said shanks at their opposite ends on the stringers of said sections, said shanks having surfaces thereon adapted to engage tially a pair of J-shaped sections pivotally connected together at their free ends and pivotally connected at their opposite ends to the stringers to permit collapsing of the sections at either side of each other.

6. Ina hinge construction a pair of sections, a hinge including a pair of hinged parts with each part including an elongated body with transverseoifsets at the ends thereof offset in opposite directions, means pivotally connecting said parts of the hinge together at the outer ends of similar offsets, and means pivotally' connecting the hinge parts to said sections atthe juncture of the bodies thereof with the other offsets so that the sections may be moved to a collapsed relation at either side of the plane of the other in a relation that when collapsed together in" one position the elongated bodies will form an abutment against said sections and when collapsed together at the opposite sides said sections will have their hinged parts in position so that the bodies are in an X-shaped relation with the offset ends thereof adjacent the respective pivots on saidsections in abutment with said sections.
